To all whom it 11mg concern:

Be it known that I, ELMER A. SPEER'Y, a citizen of the United States, residing atOleveland, county of Ouyahoga, and State of Ohio, have inventeda new and useful Improvement in Power-Gearing for Trucks, of which the following is a full, clear, and exact description.

lily invention relates to powe1--t1-ansmitting devices forvehic1es,more espeeiahjyrailwaytrucks; and it consists in certain devices for transmitting power, between the rotatin axles of such trucks or between a motor or motor devices and such axles, whereby the normal flexibility oft-he truck is not interfered with, the construction allowing-0f the independent movement of the axles with refare used in connection with short-radius,

curves, rough track-crossings, and thelike.

It furthermore consists in certain details of construction which tend to cheapen such der vices and render them more efficient.

It is fully describedin the specification and pointed out in the cla'inis, and illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a railway-truck with the power-transmitting device in place, showin some portions of the gearing in tion and the transmitting device in outline. Fig. 2 is a front elevation of the power-transmitting device. Fig. 3 is a side elevation of the same. Fig. at is a side View of the balllink, partly broken away. Fig. 5 is a large section of said link and the ba ll-and socket bearing on line a: 33, Fig. 2. Fig. 6 i's'an elevation'of the driven member; Fig. 7, an elevation of the driver. Figs. 8, 9, and 10 illustrate details of the flexible driving device. Fig. 11 is a top plan view of thetransmi'tting device when the shafts'a're separated axially. Fig. 12 is a side elevation of the same, and Fig. 13 i'sja detail showing the cushioning device for the bars which support the motor.

Let A A,Fig. 1, represent a truck-frame mounted uponbearings BB, &c., on the'out'e'r extremities "of the axles O O, supporting niitting device, preferably a beveled gear and pinion, which are suitably housed in gear-casings (indicated at D D) geared upon axles by journal-bearings D. The pinionshaft of the gear is journaled in suitable bearingsaiso located Within the gearhousing D at point D which forms, preferably, an integral portion of such gear-h'oi'is'in'g' and receives support on a cross-bar X of the truck-frame A. The'pinion-shaft protrudes from its' journal sufficiently for the proper securing of. the hub 11, carrying an arm or arms H, Which constitute the driven element and are illustrated in detail in Fig. 6. A short piece of shafting, resting in suitable bearings H, is mounted upon cross-pieces I I, secured to the truck, preferably by elastic cushions or supports 1. This shaft may or may not constitute a portion of the motor J, but it is preferably a driven shaft receiving motion from said motor. Supposing, however, that it forms a part of such motor, the motor provided with the bearings H is suitably supported on the cross-pieces I, which preferably are fiat bars with their greatest dimension vertically disposed and relatively somewhat flexible lengthwise of the truck, as is clearlyshown in dotted lines in Fig. '1, thereby allowing the motor freedom'of movement in this longitudinal direction dependent upon the amount of elasticity of said bars I. It will readily be understood that such movement will take place when the vehicle strikes any obstruction, either small 'or great, or stands upon a grade. The inertia or momentum of the mass making up "the motor J will be found to constitute afoice acting to flex the bars I in the manner de-' scribed. As this longitudinal movement of the driving or armature shaft takes place the extremities thereof close in upon or recede from the adjacent extremities ofthe pinions'ha fts. In Figs. 2 and 10 will be found details of a structure constituting a flexible driving device organized to connect the extremities of the said pinion-shaftsin such a manner asto provide for such longitudinal movement of said driving or armature shaft and at the same time not interfere in the least with its proper functions as a power-transmitting device. This device is substantially ical socket at-each end fitting the pinsP and R, substantially as described.

4. ha motor-truck, the combination with the axles, of shafts arranged lengthwise of the truck and geared to said axles, cross-bars supporting the inner ends of said shafts,other cross bars between the shaft supporting cross-bars, said latter bars being rigid vertically, but adapted to flex horizontally, in a direction lengthwise of the truck, a motor supported on said flexible cross-bars, and comprising a longitudinal driving-shaft, and flexible power-transmitting devices connecting each end of said shaft With an adjacent geared shaft, substantially as described.

In testimony whereof I have hereunt signed my name.
